ENT/Surgery: Foreign Body (FB) in Esophagus
High-Yield Revision for NEET PG
Esophageal FB impaction is a common emergency. Unlike airway FBs, these are typically not immediately life-threatening unless complications like perforation or airway compression occur.
1. Clinical Presentation
- History of ingestion (coins, food bolus, dentures).
- Symptoms: Dysphagia, odynophagia, excessive drooling (inability to handle saliva), and retrosternal pain.
- Complication Red Flags: Subcutaneous emphysema, neck swelling, or signs of sepsis (suggest perforation).
2. Common Sites of Impaction
FB impaction occurs at the anatomical narrowings, in descending order of frequency:
- Cricopharyngeus (UES): The most common site (70–80% of cases).
- Aortic Arch level (22–25 cm from incisors).
- Left Main Bronchus level (27 cm).
- Diaphragmatic Hiatus (LES) (40 cm).
3. NEET PG High-Yield Pearls
- Imaging: Most FBs are radio-opaque (coins, metallic objects). For radiolucent FBs (fish bones, plastic), soft tissue neck X-rays or CT neck may be required.
- Diagnostic/Management Tool: Rigid Esophagoscopy is the standard for removal.
- “Coin” Orientation: Coins in the esophagus lie in the coronal plane (face-on in AP X-ray); coins in the trachea lie in the sagittal plane (edge-on in AP X-ray).
- Sharp Objects: High risk of perforation; requires urgent endoscopic removal.
